IMPROVEMENT IN en -PRESS MATS.

Specification forming part of Letters Patent No. 174,432, dated March 7, 1876;' application tiled January 22, 1876.

To all whom t may concern:

Be it known that we, JOSEPH L. RERKINS and GEORGE 0. BAKER, ot Selma, Dallas county, Alabama, have invented a new and Improved Oil-Press Mat, 'of which the following is a specitication: y

vFigiue l represents a top view of our improved oil-press mat, shown in open position.

Fig. 2 is a vertical longitudinal section ot the saine on the line c c, Fig. l; andFig. 3' is a side view ot' the same, showing it in position brpressing. Y l

Similar letters of reference indicate corresponding parts.

The object of our 'invention is to furnish to the manufacturers ot' cotton-seed oil an improved mat, which, by its strength and durability, is not so liable 'to breakage as the expensive ma-ts of twistedl hair-cord lat present in use, and which will bear a more powerful pressure, so as to yield a larger percentage of oil from the seed.

The invention consists of an oil-press mat lmade of Wood or metal plates, and covered with leather or other suitable material.

In the drawing, A A -represent the wood or metallic plates ot' equal size, which are fitted to the shape of the press-box. These plates A are lined at the inside and outside -with leather, Wood, sheet-iron, or other suitable material,`B, that is not injured or decomposed by thev oil. The outside ends of the plates may be so connected by the lining B that a hinge with a handle, G, is formed for the purpose of putting the mat in and out ot' the press-box, and for holding the plates in the box in position for use. The lining'may be made to project over the edges of the Aplates sufliciently to protect the lining of the boxes from contact with the metallic plates, preventing thereby bruising and cutting by the contact of metal with metal. The inside lining ofthe plates may be used or not, as desired, as it 'has been found by actual tests that the bags holding the meal are not injured by contact with the metal plates. The plates impart to the mat the main strength, and admit thereby a higher degree ot' pressurethan the hairmats, While lasting longer and being in every respect more e'ective than the same.

Having thus described our invention, we claim as new and desire to secure by Letters Patent- An oilpress mat formed of' leather on the outside and metal on the inside, the former being carried around the edges of the latter, as and for the'purpose speoied.
